I suppose you don't know what is a Nuzlocke Challenge. It is a challenge that have three basic rules:
1 - You can only catch the first Pokémon in each area.
2 - If a pokemon faint, you must release it or put it into a "RIP" box. It cannot be used again.
3 - You must nickname every pokemon.
There are many optional rules, like a dupe clause, to prevent you from having an army of rattatas or something like that and other that permit you to caught any shiny pokemon, but I'm not using any of them. I am actually very lucky to only have two overlapping pokemon, and a diverse team.
Edit: @Topic
I'm loving every single part of this run. I have to place every step carefully with every battle. Didn't lost anything yet due to the Faint=release rule not being active on gyms, but even the trainers are challenging. Patched my ROM to 0.7 and cleared the desert today.
